WINDMILL.

SPECIFICATION forming part of Letters Patent N0. 503,652, dated August 22, 1893.

Application led February 6, 1893. Serial No. 461.163. (No model.)

To all whom it may concern.: g, l

Be it known that I, CHARLES W. CLARKE, a citizen of the United States, residing at Hanford, in the'county of Tulare and State of California, have invented a new and useful Windmill, ot' which the following is a specication.

The invention relates to improvements in Wind mills.

The object of the present invention is to simplify and improve, and increase the efficiency of wind mills, and to provide one in which the parts will counterbalance and bring the center of gravity directly over the top of the tower, whether the wind wheel be in or ou of the wind.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended.

In the drawings-Figure 1 is a perspective view of a wind mill constructed in accordance with this invention, and showing the position of the parts when the wind Wheel is in the wind.` Fig. 2 is an elevation showing the position of the parts when the wind wheel is out of the wind. Fig. 3 is a central vertical sectional view the parts being in position shown in Fig. 2.

Like numerals of reference indicate corresponding parts in all the figures of the drawings.

1 designatesa horizontalframe provided on its lower face with a turn table 2 and mounted rotatively on the top of a tower 3 which is provided with a vertical tube 4 forming a spindle for a standard 5 of the frame 1. The turn table is located at one side of the horizontal frame 1, which is provided with an opening 6 to permit a crank bend 7 of a shaft 8 to revolve freely. The shaft is journaled in suitable bearings 9 at opposite ends of the openings 6, and carries at one end, which is extended beyond the frame, a wind wheel 10. The wind wheel causes the shaft 8 to rotate and motion is communicated to a pump rod 11 by means of a pitman 12 and an oscillating lever or walking beam 13 which is fulcrumed between its ends in the bifurcation of an inclined arm 14 extending upward from the top of the standard 5. The inner end of the oscillating lever 13 is bifurcated to receive the upper end of the pump rod, and the other end of the oscillating lever is provided with a series of perforations 15, and is pivoted by a bolt to the upper end of the pitman which is adapted to be adjusted on the oscillating lever, by means of said perforations and the bolt or pin to vary the length of the stroke of the pump rod.

The standard 5 is hollow and is provided at its lower end with securing flanges which are bolted to the upper face of the horizontal frame 1, and the latter is provided with ribs 17 arranged to form a socket for the lower end of the hollow standard. The ends of the hollow standard are provided with bearings for the vertical tubular spindle 4 and extending from the top of the hollow standard is a horizontal arm 18 terminating at its outer end over one corner of the horizontal frame 1. The arm 18, and the corner of the frame vertically below it are `provided with bearing eyes and receivea pintle rod 19, which hinges a vane 2O to the frame. The vane has parallel upper and lower bars 21 and 22 extending inward from the blade to the pintle rod and beyond the same, and the bars are connected and supported by vertical bars.

The extended portions of the bars 21 and 22 have secured to them a vertical rod 23 forming a spindle or pintle for a block 24 to which is hinged a bell-crank lever 25 which is weighted, and is adapted to hold the vane at right angles to the wind wheel to keep the latter in the wind. The arm 26 of the bellcrank lever is provided at its outer end with a series of perforations 27, and is connected by a link 28 with the top of the hollow standard, and the perfor-ations permit an adjustment of the connection. The inner end of the arm 26 of the bell-crank lever is enlarged and bifurcated to receive the block 24. The arm 29 of the bell-crank lever extends from the enlarged portion of the arm' 26, and is provided with an adjustable weight 30.

The wind mill is controlled by a chain 31 having one endk attached to an arm 32 of the vane. and extending from the arm over a pnlley 33 and down the vertical tube and terminating at the base of the tower. The arm 32 extends inward from the vane at a point between the blade and the pintle rod, whereby IOO ventiOn.

when the chai-n is drawn the vane will 4be. l

turned at right-angles to the windwheeland the weighted bell-crank lever will be lifted. The pulley 33 is mounted in a bracket located at the top of the hollow standard and secured thereto. Y ,l The vane and the weighted'bell-crank lever are disposed opposite and counterbalance the wind wheel, and the parts preserve aconjtin-g ual equipoise, and as the vane is turned inward to throw the wind wheel out of the wind,` the bell-.crank 4lever moves outward ato pre-L. serve the balance. It will be seen that the wind mill is simple,'f comparativelyinexpensive and eiective, that :the stroke of the 'pum-p rod may-be readily regulated, and that the partsare .balanceditof jpreventanyflateral straining-on the tower.

yChanges yin the form, proportion and. the? `minor details of construction maybe lresorted v'to without departing Afrom the principle l'or "1 sacrificing :any yof the advantages of this -inf Y.
